Vlfhis invention relatesto a speed indicator lor autoin'ebiles.v

`The object `oilA the inventionis to provide a speed indicator ivhich,when applied on the hub ot a' vehicle iviieeL-revolves so that anannular disk is slit by centrifugaltorce to exhibit different alternate)fields in the cover of the speed indicator, ivlienthe speed oic thevehicle exceeds that for Which cerbeen adjusted ytain .Weights and abrake have on the annular disk. y

A high' speedsignal, ywhich isv'not eX- posed when driving Within towns,is provided for. locking the .disk'against sliding,

when running,- at high speed on roads Where it is allowed. y, y

travelling' in' the open f Having thus described my inveiitien what Iclaim is: ,l

l. A speed indicator i'or vehicles, coniprising an annular casing havinga 'front plate provided with transparent fields; a back plate vhavinginterior parallel channels on chord lines equidistant `from the centerot the casing, anannular disk having alternate coloured elds andprovided With grooves on its diainetrical lines, landa sliding Weight inone of theA grooves having a projection sliding in one of the channels.

Q. :A speed-indicator forxvehicles, coinprising anl annular casing`having a back plate itting on a Wheel hubv and having transparent iieldsin the cover of'said; casing, 'said` back plate having interior parallelchannels on chord-lines, equidistant from `center ot' said casing, anannular disk havfields, and said plate vbeing-'provided with grooves; adisc insaid' casing having grooves and provided with fields oi'diferentcolors; and means associated With-both` lsets of grooves for rotatingsaid disc-With'respect to saidcasing When said casing is rotated,

5. Aspeedindicator comprising casing embodying al back plate providedwith grooves and also embodying a kcover provided Withtransparentiields; a disc in said casing haviiiggrooves therein andprovided with ields of different colors;k adjustable ineans in saidcasing to `frictionall'y engage said disc; Weights associated with bothsets of grooves tor rotating said discvvith respect to said casing inorderto change the color of the disc `which is visible under saidtransparent Yfield; and means for` maintaining the indicator -in aninoperative condition. 6. A speed :indicator as claimed in. claim 5, inWhich-the means for maintaining the indicatorinoperative'coacts with'the disk to thereby prevent its rotation.
